Question

An object with an initial velocity of 20 cm/s is accelerated at 8.0 cm/s squared for 5.0 s. A) what is the total displacement? B) what is the displacement during the fifth second?

Answer 1

\[v=v_{0}+at\] i think you can use that for (A) you have v(0), a, and t. just plug them in and then you know that velocity is time over distance so using the velocity you found by using the equation you can find distance(displacement) i think think this will work.

Answer 2

and then for (B) i think you can just find the velocity of the object at 4 seconds and then divide by time and then subtract this value from the total distance(the distance you found for (A)) and that will give you the displace for the 5th second.
